Bones are composed of two types of tissue: cancellous (spongy) bone containing red bone marrow, osteocytes, and a marrow cavity surrounded by bony trabeculae and spicules, and mature compact bone containing osteons with osteocytes and Haversian canals. Endochondral bone formation occurs through the replacement of a hyaline cartilage model by forming bone, such as in the epiphyseal plate where long bones grow in length.
